The PK91 Folding Stool was designed by Kjaerholm in 1961 and incorporated flat spring steel bars and canvas or leather for the seat. The long sides of the frames formed the legs of the stool and were twisted like propellers for increased strength. In a traditional folding stool of the time, the legs were located on either side of the seat to minimize the distance spanned by the wood struts. But by twisting the legs, Kjaerholm's stool could span a wider distance and thus, he rotated the structure 90 degrees so that crossed legs formed the front and the back of the stool.

Another innovation of this PK91 folding stool was the way it folded flat. In a typical stool, the identical frames are nested one inside the other, which causes them to be offset when the stool was folded. Kjaerholm wanted his stool to appear consistent from both sides, folded or unfolded. The PK91 achieves this because of two design features: First, the points of contact between two frames consists of ball bearings flush joints. Second, the frames are mirrored parallelograms with corners of 88 and 92 degrees. The proportion of the seat conceals this distortion and creates the appearance of the identical, nested frames.

Our PK91 inspired Folding Stool incorporates all of the elements described above. In addition, we use 12mm satin-brushed 304 stainless steel for the frame with a 3mm corner radius. The seat is made with 2mm thick cowhide belting, covered with your choice of black, dark brown or white leather.
